There is this thing...
What is that thing in the upper right corner of each post that changes the structure of the message? (for example, if the post is large and centered)

Yes, I don't like this thing either... It's annoying... It ruins the appearance... Especially in styles where the background on which the message is displayed is not white, but, say, brown. Then there is a large white square.
